First make sure you have Java installed.

If you're sure you have it installed, assuming you're using windows, follow these steps:

1. Click the start button
2. Then right click computer
3. Click Properties
4. Click Advanced System Settings
5. Click Environment Variables
6. If you see JAVA_HOME, go to step 11, if not, click new
7. Variable Name = JAVA_HOME
8. Variable Value = <Location of your Java JDK> Without the <> (Usually something like C:\Program Files\Java\jdk1.8.0_25")
9. Click Ok
10. Restart Eclipse and You're Done!

I hope I could help

This is what worked for me way back when I had that problem iirc. Also, I don't think it's win10. I've got win10 and no problems.
